Information about “A-FILTER”
This program calculates the resistor and capacitor values for various
operational amplifier based active filter circuits. A-FILTER is menu-
driven and covers high and low pass, equal value Sallen-Key filters to
the 4th order.
Calculations will simultaneously include seven response curves for each
filter (greater than 1st order); best delay, compromise, flattest,
slight dips, 1db dips, 2db dips and 3db dips.
The screens are laid out in a format similar to the illustrations in
"The Active Filter Cookbook" by Don Lancaster. The screens refer to
pages in the book which show the shape of each curve. Although it is
not necessary to have this book to run A-FILTER, the book provides
valuable additional information.

Calculations will simultaneously include 7 response curves for each filt
(greater than 1st order); Best delay, Compromise, Flattest, Slight dips,
1db dips, 2db dips and 3db dips. These filter configurations can be cas
to make bandpass filters.
